Deficit financing
● The act/process of financing/supporting a deficit budget by a government is deficit financing. It is done by external or internal burrowing or by printing currency.

Printing fresh currencies does have other damaging effects on the economy:
● It increases inflation proportionally. (India regularly went for it since the early 1970s and usually had to bear double digit inflations).

India’s engagement with the Arctic began when it signed the Svalbard Treaty in February 1920 in Paris between Norway, the US, Denmark, France, Italy, Japan, the Netherlands, Great Britain, and Ireland, and the British overseas Dominions and Sweden concerning Spitsbergen. Ever since then, India has been closely monitoring all the developments in the Arctic region.
India has launched its first winter expedition to Himadri, its Arctic Research Station at Ny-Ålesund in the Norwegian archipelago of Svalbard. The station, which was previously operational for about 180 days annually, will now remain operational throughout the year. This move makes India one of the few countries to operate its Arctic research bases during winter.
